[huddo R33]

atm im trying to figure out what had been done to my engine befor i send it in to get tuned so far i know
3.5" turbo bac kakimoto racing exhaust with highflow cat
fmic
ally radiator
judging but the tortion bar and sound of the car i think is has some sort of cams cant realy tell unless i wanted to rip em out

my main questions are with my fuel rail and injectors
what is the colour of a stock fuel rail for a rb25det and what colour are the injectors
currently it has a green fuel rail and purp injectors im pretty sure they are aftermarket

also pretty sure that this car is an m spec 40th aniversary model

type m is R33/32, M spec is version of R34GTR.

Pretty sure youres isnt a 40th Anniversary Edition. Stock fuel line is copper-ish, so grean/blue/brown coloured.
Take the rocker cover off and have a look at the cams, not too hard to work it out.

really isnt possible to give u a real idea without seeing the car or atleast photos.
but your R33 basically sounds stock. i wouldnt waste my money on a tune for a stock car.

pic of engine bay is the only way to really know but, r33 stock injectors are purple, by green fuel rail im assuming u mean thats its a faded moldy greeny/gold colour which is stock.
can guarantee you wont have an aftermarket fuel rail if u have stock intake manifold.
heres a stock fuel rail with injectors that i prepared earlier..

the dark purple injectors in the rail are stock the ones.

pretty safe to say your car wont have cams if u dont even have aftermarket injectors or turbo.
it may idle lumpy depending on your timing.

before u spend your hard earned cash on a dyno tune:
first step
-see what ecu you have- upgrade -even one of those ebay mines chips will do -can get rid of speed limiter etc
-see what fuel pump you have- upgrade fuel pump to minimum bosche 040

go from there ^^
after u upgrade ur fuel pump and ecu everything after that ie injectors turbo etc is gonna cost u over $1000

How are you planning on tuning the standard ECU anyway?
And Char pretty much backed up what I said and what I was thinking, lol

[huddo R33]

not tuning getting a new ecu adn the injector is the same colour as thw one in the buble wrap so light purp
wanna do new ecu now not a chip or pigy back so i dont have to re spend money later
